Web Site Recreates Apollo 11 Mission In Real Time

Apollo 11

From Yahoo News/AP:

Families crowded around black-and-white television sets in 1969 to watch Neil Armstrong take man's first steps on the moon.

Now, they'll be able to watch the Apollo 11 mission recreated in real time on the Web, follow Twitter feeds of transmissions between Mission Control and the spacecraft, and even get an e-mail alert when the lunar module touches down. Those features are part of a new Web site from the John F. Kennedy Presidential Library and Museum commemorating the moon mission and Kennedy's push to land Americans there first.

"Putting a man on the moon really did unite the globe," said Thomas Putnam, director of the JFK Library. "We hope to use the Internet to do the same thing."

The Web site — WeChooseTheMoon.org — goes live at 8:02 a.m. Thursday, 90 minutes before the 40th anniversary of the Apollo 11 launch from Cape Canaveral, Fla. It will track the capsule's route from the Earth to the Moon, ending with the moon landing and Armstrong's walk — in real time, but 40 years later.

From Washington Post:

Plan to 'De-Orbit' in 2016 Is Criticized.

A number of times in recent weeks a bright, unblinking light has appeared in the night sky of the nation's capital: a spaceship. Longer than a football field, weighing 654,000 pounds, the spaceship moved swiftly across the heavens and vanished.

Fortunately, it was one of ours.

The international space station is by far the largest spacecraft ever built by earthlings. Circling the Earth every 90 minutes, it often passes over North America and is visible from the ground when night has fallen but the station, up high, is still bathed in sunlight.

Hungry Cats Trick Owners With Baby Cry Mimicry

From New Scientist:

Cat owners will know the feeling. Your pet is purring loudly, demanding to be fed, and isn't going to give up until it gets what it wants. What most doting owners won't realise is that the cat is using an acoustic ruse.

According to Karen McComb of the University of Sussex, UK, domestic cats hide a plaintive cry within their purrs that both irritates owners and appeals to their nurturing instincts.

From Breitbart/AFP:

A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday.

Previous research into this period, called the Palaeocene-Eocene Thermal Maximum, or PETM, estimates the planet's surface temperature blasted upwards by between five and nine degrees Celsius (nine and 16.2 degrees Fahrenheit) in just a few thousand years.

This Is Why the Shuttle Launch Is Delayed

From Popsci.com:

It's hard to launch a Space Shuttle when the launch pad keeps getting struck by lighting. NASA cameras caught 11 lightning strikes, including one direct hit to the pad, near the space shuttle Endeavour's launch pad, during a thunderstorm on July 10.

The storm forced the space agency to call for a 24-hour delay to inspect the shuttle for possible damage. One spectacular strike even hit the top of the launch pad's lightning rod, which channeled the electricity harmlessly away from the shuttle through a series of metal wires.

From The Telegraph:

A man suffering from pancreatic cancer – one of most deadly forms of the disease and which has also struck Dirty Dancing star Patrick Swayze – has been given hope of long-term survival after being treated with an advanced form of radiotherapy.

Robert Ferrant, 62, who is one of the first in Britain to undergo the procedure, was given just a few months to live after he was diagnosed with the condition.

Only 13 per cent of people who contract it are alive a year after diagnosis and only three per cent surviving for five years.

From The Guardian:

Pictures from a Nasa mission reveal new glimpses of a world as fantastic as any imagined by a science-fiction writer.

Scientists have picked the first crew of Earthlings to fly to another planet. Those chosen for a Mars mission to be launched in October include specimens of thale cress and brewer's yeast, and a microbe known as Conan the Bacterium.

Together with several other microscopic organisms, these representatives of earthly life will be carried in a package that will be flown on a Russian robot spacecraft and are scheduled to be returned to Earth in 2012. The experiment - Living Interplanetary Flight Experiment, or Life - is designed to show if living organisms can survive unprotected in space for long periods and thus support the theory of panspermia, which argues that simple organisms can survive for years as they float through space and that life on Earth could have been wafted here from another world.

Is Grapefruit Juice Toxic?

From Live Science:

This Week's Question: My daughter heard that grapefruit juice can be toxic for some people. Is that true?

The juice, itself, is not toxic, but you should be careful taking medicine with any grapefruit.

Grapefruit juice can raise the level of some medications in the blood. The effect of grapefruit was discovered after using juice to mask the taste of a medicine. So, be sure to ask your doctor or pharmacist if it is safe to have grapefruit with your medications.

Taking medicine can be hazardous to your health. You have to know what you're doing.

From New Scientist:

EACH clear night when the moon is high in the sky, a group of astronomers in New Mexico take aim at our celestial neighbour and blast it repeatedly with pulses of light from a powerful laser. They target suitcase-sized reflectors left on the lunar surface by the Apollo 11, 14 and 15 missions, as well as by two Russian landers.

Out of every 300 quadrillion (1015) photons that are sent to the moon, about five find their way back. The rest are lost to our atmosphere, or miss the lunar reflectors altogether.

Multi-Galaxy Collision Caught in Action

From Wired Science:

Four galaxies are involved in this pile-up 280 million light years from Earth. The bright spiral galaxy at the center of the image is punching through the cluster at almost two million miles per hour.

That speeding galaxy may be what is causing the curved swath of X-rays, shown in blue near the center of the image, which were captured by NASA’s orbiting Chandra X-ray Observatory. The three other yellowish galaxies in the collision are optically visible and were imaged by the Canada-France-Hawaii Telescope on the summit of the dormant Mauna Kea volcano in Hawaii.

Human History Written in Stone and Blood

Figure 1. Hunter-gatherer people living in southern Africa in the Middle Stone Age left behind artifacts in natural rock shelters and caves. At top is Sibudu Cave, located about 40 kilometers north of Durban. Below that is Ntloana Tsoana, a rock shelter located on the south bank of the Phuthiatsana River in the Lesotho highlands. At bottom, right of center in the photo, is Blombos Cave, located about 300 kilometers east of Cape Town. That’s where archaeologists found artifacts representing innovative behavior previously thought to have emerged in Europe much later. Improved dating of such artifacts helped the authors evaluate what contemporary factors might have contributed to the origins of modern human behavior. Top photograph courtesy of Lyn Wadley. Middle photograph courtesy of Richard Roberts. Bottom photograph courtesy of Chris Henshilwood.

From American Scientist:

Two bursts of human innovation in southern Africa during the Middle Stone Age may be linked to population growth and early migration off the continent

In the past decade it has become clear that symbolic expression associated with modern human behavior began in Africa, not Europe. And it occurred tens of thousands of years earlier than was once thought. Answering why is difficult. A first step was more reliable dating of when culturally and technologically advanced people lived during the Middle Stone Age in the south of Africa. Zenobia Jacobs and Richard G. Roberts accomplished that dating, which prompted them to reject climate change as a primary cause for the advancements. Instead, drawing on genetic research, they embrace population growth as a likely, key influence.

Herschel Shows Breadth Of Vision

Herschel-SPIRE's view of M74 (R) compared with that of Nasa's Spitzer space telescope. The larger mirror on Herschel (3.5m vs 0.85m) pays dividends, and will allow the European telescope to build on Spitzer's discoveries.

From The BBC:

Europe's Herschel space observatory is set to become one of the most powerful tools ever to study the Universe.

The "first light" data from its three instruments demonstrates a remarkable capability even though their set-up is still not complete.

Galaxy images released on Friday by the European Space Agency show detail previously unseen in the objects.

The pictures - and the thousands that will follow - should give new insights on star formation and galaxy evolution.

"We have some excellent images; they're not calibrated, but they look spectacular," said Dr Göran Pilbratt, Esa's Herschel project scientist.

"They tell you we are working; it's just fantastic," he told BBC News.

Machines That Heal

Arms of Steel John B. Carnett

From Popsci.com:

In the movies, entrusting human life to robot helpers and sophisticated machines inevitably ends in fire, destruction and death.

But in reality, the automatons are actually saving lives. Take the devices here: the hulking robot arms that rehabilitate stroke victims, the laser beam that calms Parkinson’s tremors, and the android that can fix you toast when you’re sick. Even the scary-looking, mind-reading skullcap will one day let paralyzed people turn on the lights just by thinking about it. No fire, no destruction, no death—just eye-popping technology and better medical care.

From Technology Review:

An improved catalyst could help oil refineries get more gasoline out of a barrel of crude petroleum.

In an effort to make gasoline production cleaner and more efficient, Rive Technology of Cambridge, MA, is developing a catalyst that can help turn a greater percentage of crude petroleum into gasoline and other usable products. The company, which is testing the catalyst in its pilot plant in South Brunswick, NJ, believes that the technology will be able to process lower-grade fossil fuels and reduce the amount of energy that goes into the refining process.

New Kind Of Astronomical Object Around Black Hole: Living Fossil Records 'Supermassive' Kick

This artist's conception shows a rogue black hole that has been kicked out from the center of two merging galaxies. The black hole is surrounded by a cluster of stars that were ripped from the galaxies. New calculations by David Merritt, from Rochester Institute of Technology, Jeremy Schnittman, from Johns Hopkins University, and Stefanie Komossa, from the Max-Planck-Institut for Extraterrestrial Physics in Germany suggest that hundreds of massive black holes, left over from the epoch of galaxy formation, are waiting to be detected in the nearby universe. (Credit: Space Telescope Science Institute)

From Science Daily:

ScienceDaily (July 10, 2009) — The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick.

A paper published in the July 10 issue of The Astrophysical Journal discusses the theoretical properties of “hypercompact stellar systems” and suggests that hundreds of these faint star clusters might be detected at optical wavelengths in our immediate cosmic environment. Some of these objects may already have been picked up in astronomical surveys, reports David Merritt, from Rochester Institute of Technology, Jeremy Schnittman, from Johns Hopkins University, and Stefanie Komossa, from the Max-Planck-Institut for Extraterrestrial Physics in Germany.

Swearing Makes Pain More Tolerable

From Live Science:

That muttered curse word that reflexively comes out when you stub your toe could actually make it easier to bear the throbbing pain, a new study suggests.

Swearing is a common response to pain, but no previous research has connected the uttering of an expletive to the actual physical experience of pain.

"Swearing has been around for centuries and is an almost universal human linguistic phenomenon," said Richard Stephens of Keele University in England and one of the authors of the new study. "It taps into emotional brain centers and appears to arise in the right brain, whereas most language production occurs in the left cerebral hemisphere of the brain."
